Abstract

Embodiments are directed toward a helmet including a receiver for adjustably securing a mask. The mask includes a bayonet to be received by the receiver. The receiver includes a bayonet coupler and a plate pressed against the coupler. The coupler has a channel for releasably engaging the bayonet of the mask mount. The plate is fixedly secured to the helmet shell outboard of the coupler. The coupler is rotatably secured to the plate, the coupler having a pin extending outwardly therefrom through the plate and to the exterior of the helmet shell.

         21 . A receiver securable to a helmet having a shell for adjustably securing a mask having a mask mount, the receiver comprising:
 a coupler for releasably engaging the mask mount, the coupler being positioned inside the helmet shell; and   a plate for fixed securement to the helmet, the plate being positioned inside the helmet shell;   wherein the coupler is rotatably secured to the plate.   
     
     
         22 . The receiver of  claim 21 , wherein the plate is an outer plate relative to the coupler, the coupler being positioned on the inner side of the plate and being rotatable relative to the plate and helmet. 
     
     
         23 . The receiver of  claim 22 , wherein the plate is fixed directly to the helmet shell. 
     
     
         24 . The receiver of  claim 23 , wherein the plate includes at least two bosses that extend outwardly from an outer face of the plate, the bosses adapted to extend through openings in the shell and having inner openings for receiving fasteners for fixed securement to the helmet shell. 
     
     
         25 . The receiver of  claim 22 , further comprising a coupler adjustment mechanism for adjusting the angular position of the coupler relative to the plate, the coupler adjustment mechanism being accessible from the outside of the helmet shell. 
     
     
         26 . The receiver of  claim 22 , further comprising an adjustment angle indicator showing the position of the coupler relative to the shell. 
     
     
         27 . The receiver of  claim 26 , wherein the indicator includes markings on the helmet shell. 
     
     
         28 . The receiver of  claim 22 , further comprising a pin extending from the coupler through the plate, the plate having a hole therein for rotatably receiving the pin, the pin being long enough to extend through the plate and through the helmet shell once the receiver is secured to the helmet. 
     
     
         29 . The receiver of  claim 28 , wherein the pin is keyed, the receiver further including a washer keyed to the pin and having an indicator marker to track the rotation of the coupler relative to the plate and helmet. 
     
     
         30 . The receiver of  claim 29 , wherein the pin is a threaded bolt, the receiver further including a threaded nut rotatably secured to the threaded bolt for locking the rotational adjustment of the coupler to the plate. 
     
     
         31 . The receiver of  claim 22 , further comprising a tightening member to pull the coupler towards the plate to hold the angular position of the coupler relative to the plate. 
     
     
         32 . The receiver of  claim 21 , wherein the coupler includes a channel for receiving a bayonet member of the mask mount, the channel having a forward opening receiving end including guide ramps for directing the insertion of the bayonet member. 
     
     
         33 . A helmet including a receiver for adjustably securing a mask having a mask mount including bayonets, the helmet comprising:
